I liked SCH in FFXI. It was a very interesting class that was actually added to be sj. SCH brought to XI the flexibility the game was lacking due the fail skill system. Was very nice for, as example, having higher tier nukes to combo with DRK elemental skills oe allowing SMN to use enfeebling magic even without enfeebling skills.

Also, sublimation was a godsend skill. Too bad SCH was just an awesome sj, not really being better than any color mage when disputing a role.

And talking about SCH here, it prolly would actually used a grimoire as weapon, like in FFT...after all the grimoire is the SCH weapon.
